if u wanna impress, u got to keep it old school know wat i mean? for example, u can wear a fresh white-t and some cresed up khakies with some white shoes(clean them so it reflects the sun on ur face) or a black shirt with black shorts, (white) long sox and some black n white shoes such as NIKE CORTEZE'S and of course A BLUE RAG in your pocket or your shoulder
the final touch, just shave your head every day or comb ur back (oviously ull need gel or just wear a hair net)
and always keep ur chin up
